[reportlab-users] Problems with drawImage()

Thu Feb 9 10:19:10 EST 2006

I am having problems using drawImage() to insert an image (PNG) file
into my PDF when the function is embedded in a script. My script looks
like this:
******************
print 'Content-type: text/html\n'
import sys
from reportlab.pdfgen import canvas

print "<html><head><title>PDF Generation</title></head><body>"
c=canvas.Canvas("test.pdf")
c.drawImage("/var/www/html/tmp/select.png", 15, 150, width=200,
height=100)
c.showPage()
c.save()
print "</body></html>"

********************

When I enter these commands at the Python prompt, the PDF file is
created exactly as I have specified. However, when I execute the
identical script, or I run it through a web browser, I get the following
error messages:

*************************************

Content-type: text/html

<html><head><title>Fun with Stubby</title></head><body>
Traceback (most recent call last):

Any help would be greatly appreciated.
